An economic model of the iron ore trade
Iron ore is among the biggest, non-energy extractive industry in the world in terms of value, and the biggest in terms of the volumes of cargo it channels in international trade. Two key characteristics of the iron ore market are central to its study: firstly, there is only a small number of buyers …

Compositions, logratios and geostatistics: An application to iron ore
… methods, kriging and simulation, ignore the fact that geochemical data are usually reported in weight percent, sum to a constant, and are thus compositional in nature. The constant sum implies that rescaling has occurred and this can be shown to produce spurious correlations. …

Direct reduction of iron ore in a rotary kiln
Brazilian hematite iron ore was reduced successfully in a rotary kiln with a gaseous reactant which was prepared by reforming butane within the kiln, using the beneficial effect of iron/iron oxide as an autocatalyst. The optimum ratio of the gaseous reactants, H2/CO2/C4H10, was used to prevent …

Internet of Things and anomaly detection for the iron ore mining industry
… IoT technology to the reduction of costs in the iron ore mining industry, to compensate for the iron ore price slumping observed over the past years. More specifically, we focused on improving the quality of the output in a data-driven iron ore concentration factory. In this plant, mined iron ore …

Prospects for Liberian iron ores considering shifting patterns of trade in the world iron ore industry.
… examines the performance of the Liberian iron ore industry from 1950-1985 and its viability in global markets, assuming stagnation (World Bank) and expansionist (Leontief et al.) expectations. It examines past trends in trade and investment patterns in the light of equilibrium allocations …

Energy efficiency and carbon dioxide emissions across different scales of iron ore mining operations in Western Australia
During the last two decades, Western Australian iron ore mining industry experienced an exponential production growth arising from increased global demand for steel. The upturn in the iron ore price and considerably lower production cost encouraged extensive mining and consequently high-grade ore …

Application of Measurement While Drilling Data for Mine Blast Optimization Utilizing Machine Learning Techniques with Iron Ore Mine Data
… within a rock mass is very unpredictable so to more accurately determine its characteristics a controlled drilling environment is needed. Many mines possess the capacity to record Measurement While Drilling (MWD) data but don't utilize it. This project investigates and analyzes MWD data from an …

Investigating collector and depressant performance in the flotation of selected iron ores
As the excessive extraction of high grade iron ore reserves has led to the rapid depletion of these ore bodies, there is a growing need to extract and upgrade low grade iron ores into more economically viable products with an iron content in excess of 50%. The beneficiation of low grade iron ores …

Assessing the effect of cone ratio, feed solids concentration and viscosity on hydrocyclone performance
… cannot be optimised or operated efficiently. Ores that are mined in industry contain metals of varying specific gravity, which makes recovery of the desired metal challenging. This study focussed on the effect of the hydrocyclone spigot to vortex finder diameter ratio, termed as the cone …

Processing factors contributing to growth and decline in the steel industry
… casting began to replace ingot casting. Iron ore price, scrap steel price and electricity price were examined as predictor variables for these technological shifts. For the furnace shift, iron ore price and scrap steel price seemed to play a role, though much smaller than the role of …
